Vagrantのguest additionのエラーをvagrant-vbquestプラグインで解消する

以前、vagrant boxを自前で作成するときに、以下のエラーが出ていた。

Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:

mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` vagrant /vagrant

The error output from the last command was:

stdin: is not a tty
mount: unknown filesystem type 'vboxsf'

これは、guest addtionがインストールされていないときなどが原因で、ホストOSとゲストOSのフォルダ共有ができないときに出力されるエラーだ。

ゲストにguest addtionを入れ直せば解決するのだが、入れ直すときには、他のパッケージが必要な場合や再コンパイルが必要になり、なかなか大変だ。そこで、vagrant-vbquestプラグインを使用したい。

dotless-de/vagrant-vbguest · GitHub

vagrant-vbguestはquest addtionsをインストールに必要なパッケージと共に、自動的にインストールしてくれるとても便利なプラグインだ。実際に使わない手はない。

では実際にvagrant-vbguestをインストールして試してみる。

$ vagrant plugin install vagrant-vbguest
Installing the 'vagrant-vbguest' plugin. This can take a few minutes...
Installed the plugin 'vagrant-vbguest (0.10.0)'!

そして、このままvagrant upしてみます。ログが長いの一部省略しています。
